Tixraaca habaynta ololka dib u dhigista ee xabagta

Naqshadeynta ololka dib u habeynta ee koollada waxay u baahan tahay in la habeeyo iyadoo lagu salaynayo nooca maaddada xabagta (sida resin epoxy, polyurethane, acrylic, iwm.) iyo xaaladaha codsiga (sida dhismaha, elektiroonigga, baabuurta, iwm.). Hoos waxaa ku yaal qaybo habaysan oo dab-demis ah oo caadi ah iyo hawlahooda, kuwaas oo daboolaya xalalka dab-demiska halogenated iyo halogen-la'aanta labadaba.

1. Mabaadi'da Naqshadeynta Ololka Dib u Celinta Xabagta

• Waxtarka sareLa kulan UL 94 V0 ama V2.
• Waafaqid: Dab-demiska ololku waa inuu la jaanqaadaa walxaha saldhigga ah iyada oo aan wax saameyn ah ku yeelan waxqabadka isku xirnaanta.
• Saaxiibtinimada deegaankaMudnaanta sii dabciyaasha ololka aan halogen lahayn si ay ugu hoggaansamaan xeerarka deegaanka.
• Geedi socodka: Dab-demiska ololku waa inuusan faragelin habka daweynta koollada ama socodka socodka.

2. Samaynta Xabagta Dabka ee Halogenated

Dib-u-celiyayaasha ololka halogenaysan (tusaale, brominated) waxay kala gooyaan falcelinta silsiladda gubashada iyagoo siidaaya xag-jirayaasha halogen, iyagoo bixinaya waxtarka dib u dhigista ololka sare.

Qaybaha samaynta:

• Qalabka Saldhigga Xabagta: Epoxy resin, polyurethane, ama akril.
• Dib-u-dhigista Ololka Burbursan: 10-20% (tusaale, decabromodiphenyl ether, brominated polystyrene).
• Antimony Trioxide (Synergist): 3-5% (waxay kordhisaa saamaynta ololka).
• Balaastiiste: 1-3% (waxay hagaajisaa dabacsanaanta).
• Wakiilka Daawaynta: Lagu doortay iyadoo lagu salaynayo nooca xabagta (tusaale, amine-ku-salaysan xabagta epoxy).
• Miraha: Sida loo baahdo (wuxuu hagaajiyaa viscosity).

Astaamaha:

• Faa'iidooyinka: Hufnaanta dab-demiska sare, qadar yar oo lagu daro.
• KhasaaroWaxaa laga yaabaa inay soo saaraan gaasas sun ah inta lagu jiro gubashada; welwelka deegaanka.

3. Samaynta Xabagta Dabka ee Halogen-free

Halogen-free olol retardants (tusaale, fosfooraska ku salaysan, nitrogen-ku salaysan, ama hydroxides inorganic) waxay ka shaqeeyaan falcelinta endothermic ama samaynta lakabka ilaalinta, oo bixiya waxqabad deegaan oo wanaagsan.

Qaybaha samaynta:

• Qalabka Saldhigga Xabagta: Epoxy resin, polyurethane, ama akril.
• Fosfooraska ku salaysan ololka: 10-15% (tusaale,ammonium polyphosphate APPama fosfooraska cas).
• Retardant Olol ku Salaysan Nitrojiin: 5-10% (tusaale, melamine cyanurate MCA).
• Hydroxides aan organic: 20-30% (tusaale, aluminium hydroxide ama magnesium hydroxide).
• Balaastiiste: 1-3% (waxay hagaajisaa dabacsanaanta).
• Wakiilka Daawaynta: Lagu doortay iyadoo lagu salaynayo nooca xabagta.
• Miraha: Sida loo baahdo (wuxuu hagaajiyaa viscosity).

Astaamaha:

• Faa'iidooyinka: Deegaanka saaxiibtinimo leh, aan lahayn qiiqa sunta ah, u hoggaansan xeerarka.
• KhasaaroWaxtarka hoos u dhigista ololka, xaddi badan oo lagu daro, waxay saameyn kartaa sifooyinka farsamada.

4. Tixgelinta Muhiimka ah ee Nakhshadeynta

• Xulashada Ololka Retardant:
  • Halogenated: Waxtarka sare laakiin waxay keenaysaa khataraha deegaanka iyo caafimaadka.
  • Halogen-Bilaash: Saaxiibtinimo deegaan laakiin waxay u baahan tahay tiro ka badan.
• Waafaqid: Hubi in dib u dhigista ololku aanu keenin delamination ama aanu yarayn waxqabadka isku xidhka.
• Geedi socodkaKa fogow faragelinta daaweynta iyo socodka.
• U Hogaansanaanta DeegaankaDoorbida xulashooyinka halogen-la'aanta ah si aad ula kulanto RoHS, REACH, iwm.

5. Codsiyada caadiga ah

• DhismahaXirmooyinka dabka u adkaysta, xabagta qaabdhismeedka.
• ElektroonigaXabagta koollada korantada ee looxa wareegga, xabagta korantada.
• BaabuurXabagta nalka hore, xabagta gudaha.

6. Talooyinka Hagaajinta Habaynta

• Kobcinta Dib u Dhaca Ololka:
  • Isku-darka isku-dhafka ah (tusaale, halogen-antimony, fosfooraska-nitrogen).
  • Dib-u-celinta ololka Nano (tusaale, nano magnesium hydroxide ama dhoobo nano) si loo hagaajiyo waxtarka loona yareeyo qadarka lagu daro.
• Hagaajinta Guryaha Makaanikada:
  • Tougheners (tusaale, POE ama EPDM) si kor loogu qaado dabacsanaanta iyo iska caabinta saamaynta.
  • Xoojinta buuxinayaasha (tusaale, fiber galaas) si loo kordhiyo xoogga iyo adkaanta.
• Dhimista Qiimaha:
  • Kordhi saamiga dib u dhigista ololka si loo yareeyo isticmaalka inta aad buuxinayso shuruudaha.
  • Dooro agabka waxtarka leh (tusaale, dab-demiska guriga ama isku-dhafka ah).

7. Shuruudaha Deegaanka iyo Xeerarka

• Dib-u-dhigeyaasha Ololka Halogenated: Waxay ku xaddidan tahay RoHS, REACH, iwm.; si taxadar leh u isticmaal.
• Halogen-Free Flame Retardants: U hoggaansanaanta xeerarka; isbeddel mustaqbalka.

8. Kooban

Qaababka dib u dhigista ololka xabagta waa in lagu saleeyaa codsiyo gaar ah iyo shuruudo sharciyeed, iyadoo la kala dooranayo xulashooyinka halogenated ama halogen-la'aanta ah. Dib-u-celinta ololka halogenated waxay bixiyaan waxtar sare laakiin waxay keenaan khataro deegaanka ah, halka beddelka halogen-la'aanta ah ay yihiin kuwo saaxiibtinimo leh laakiin waxay u baahan yihiin xaddi dheeraad ah oo lagu daro. Iyadoo la wanaajinayo habaynta iyo hababka, wax qabad sare, deegaan saaxiibtinimo, iyo xabag dab-demis ah oo kharash-ool ah ayaa loo horumarin karaa dhismaha, elektiroonigga, baabuurta, iyo warshadaha kale.
